Title: Sectored voice channels with rear lobe protection
Inventor: HANLEY DONALD VINCENT
IPC: H04W36/06
Filed: 1990-11-07
Granted: 1999-03-23
Abstract: An improved method of initiating handoffs between sectors so as to reduce sectored voice channel interference is disclosed.  The sectors that are adjacent and to the rear of the sector that is serving the mobile unit are scanned for signal quality.  A handoff request message is sent to the cell controller if the signal quality detected by any of the scanned sectors is better than the signal quality read at the sector serving said mobile unit.  When the handoff request message is received at the cell controller, a voice channel is allocated to the cell and sector associated with the scanned sector specified as having the better signal.  A handoff process from the voice channel currently serving the mobile unit to the newly allocated voice channel in said specified sector, is then initiated.

Inventor: FERRAR CARL M
IPC: G01C19/72
Filed: 1991-05-24
Granted: 2001-03-20
Abstract: In a fiber optic rotation sensor having a pair of light waves counter- propagating in an optical waveguide loop, a phase modulator is driven by a modulating signal at the loop eigenfrequency. Upon exiting the loop the waves are combined into a light intensity signal which is sensed, the sensed signal including a component in  quadrature with a desired rotation rate component, the magnitude of the quadrature component being proportional to any deviatio ns in the frequency of the modulating signal from the loop eigenfrequency. The phase modulator is servo-controlled so as to drive the quadrature component to zero, thereby compensating for any deviations in the modulator frequency from the loop eigenfrequency.

Title: Drain trap
Inventor: LAI SHU-YING
IPC: E03C1/282
Filed: 1993-04-06
Granted: 1995-11-07
Abstract: A drain trap includes an L-shaped inlet tube, a cap, a vertical discharge tube and a garbage blocking member. The inlet tube includes a vertical portion, a horizontal portion having an end integral with the lower end of the vertical portion, an open upper end and an open lower end. The cap closes the open lower end of the inlet tube so that water falling from the open upper end of the inlet tube strikes an inner wall of the cap. The discharge tube has an open upper end and is connected securely to  the upper surface of an intermediate section of the horizontal portion of the inlet tube so that the drain trap is generally F-shaped,  thereby defining a return area in the horizontal portion of the inlet tube near the cap. The return area permits water that is blocked by the inner wall of the cap to flow upward into the discharge tube.          The garbage blocking member is fitted detachably in the intermediate section of the horizontal portion of the inlet tube under the discharge tube. Accordingly, water flows through  the garbage blocking member from the inlet tube to the discharge tube two times so as to hold garbage on the garbage blocking member for disposal.

Abstract: A round baler includes an expansible, upwardly converging wedge shaped bale chamber having an opening at its bottom and being formed in part by first and second belt runs that respectively converge upwardly from first and second belt support rolls respectively located at the front and rear of the inlet opening.  Expansion of the baling chamber works against a downwardly biased tensioning frame pivotally mounted to opposite side walls, the first and second belt runs extending between a fixed and a pivotal roll carried by the frame with the pivotal roll being controlled to move closer to the fixed roll as the tensioning frame is forced upwardly by a growing bale.  A fingered rake structure bridges the gap between the fixed and pivotal rolls to keep crop material from exiting the chamber. A crop braking structure is mounted above the first belt support roll and includes fingers projecting downwardly between the belts of the first run of belts and into the opening to the chamber to impede the flow of crop being carried downwardly by the first run of belts.  An alternate feeding structure may be mounted to the baler below and rearwardly of the first belt support roll and includes feeding lugs extending through slots defined by stripper vanes, the vanes having ends of the crop braking fingers received therein and cooperating with the fingers to form a smooth crop engaging surface.
